Tang-e Sulak or Sarvak is an ancient valley located in Kohgiluyeh and Boyer-Ahmad province of Iran. This beautiful area with tall mountains and oak trees goes back to Parthian Empire of ancient Perisan Empire. There are still huge relics remaining in the area which shows a king and his soldiers and ceremonial activities. This place is really scenic, specially in spring when there are lots of beautiful trees and flowers. I invite everyone to visit Iran and explore different parts of this ancient and historic land and discover many wonderful places that are there to be seen.
